RIB FOR UMBRELLAS.

Specification of Letters Patent.

[Application filed March 11, 1905. Serial No. 249,648-

To all whmn it may concern:

Be it known that I, MIOHAEL G. MoGUIRE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Ribs for Umbrellas, of which the following is a specification.

This invention relates to umbrella-ribs for use for that class of umbrellas without the inner rib elevating and lowering ferrule; and the object thereof is to construct an umbrella-rib of a plurality of pivotal sections capable of spreading apart with respect to each other when the umbrella is extended and adapted to nest one within the other when the umbrella is closed, and by such an arrangement increased strength is given to the rib when the umbrella is extended, so as to prevent the turning inside out of the umbrella, and owing to the nesting-of the sections when the urnbrella is closed it enables the umbrella to be folded in compact form, so that the umbrella can be readily inclosed within a case, which may serve when desired as a cane or a whipstock. Y

The invention further aims to provide a new construction of umbrella-rib, hereinafter more specifically described, which shall be simple in its construction, strong, durable, efficient in its use, and comparatively inexpensive to manufacture.

ith the foregoing and other objects in view the invention consists of the novel combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings, which form a part of this specification and wherein is shown the preferred embodiment of an umbrella-rib constructed in accordance With this invention; but it is to be understood that changes, variations, and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings,

which show the adaptation of the rib for use with an umbrella, and in which Figure 1 is a view of a portion of an umbrella when extended or raised, showing the application of the ribs in accordance with this invention. Fig. 2 is a vertical sectional view showing the umbrella closed and placed with- U-shaped in cross-section.

in a cane, which may be used as a case. Fig. 3 is an enlarged view of the preferred form of rib when extended, and Fig. 4 is an elevation of a modified form of rib.

An umbrella-rib constructed in accordance with Fig. 3 of the drawings comprises two sections, one of which is termed the mainsection and the other of which is termed the auxiliary section. Said main section is of greater length than said auxiliary section. The main section is indicated by the reference character 1 and the auxiliary section by the reference character 2. The auxiliary section 2 is preferably cylindrical in crosssection and is adapted to nest within the main section, the latter being what may be termed One end of the auxiliary section 2 is pivotally connected, as at 3, to the main section 1. The main section 1 is reinforced for such purpose. The other end of the auxiliarysection2 is provided With a shoulder 4 and a hook 5. The shoulder 4 acts as a stop for the movement in one direction of the auxiliary section 2, and the hook 5 acts as a stop for the movement of the section 2 in an opposite direction. The hooked end of the auxiliarysectionZ is loosely connected with the main section 1 through the medium of aband 6, which is so positioned that it will be interposed between the shoulder 4 and the hook 5. The main section 1 has secured thereto, as at 7, a flexible bracing medium 8, which will be hereinafter referred to.

The reference character 9 denotes a handle or knob, and 10 the staff of a hollow cane. The handle 9 is removably connected to the lower end of the cane.

The shaft of the umbrella is indicated by the reference character 11, which is preferably formed of a steel rod or tube, but may be formed of any other suitable material.

12 denotes a support which is rigidly secured to the shaft 11 near the upper end thereof.

13 indicates a ferrule which is slidably mounted upon the shaft 11.

14 denotes a cord, the upper end of which is secured to the ferrule 13, and the other end may be provided with a handle 15.

The ribs of the umbrella are pivotally connected to the ferrule 13, as at 16, and the upper ends of the flexible bracing mediums 8 are fixedly connected to the support 7.

When it is desired to use the umbrella, the same is removed from its position in the staff and opened by pulling downwardly upon the cord 14, which causes the bracing mediums 8 to become taut, and, furthermore, causes the spreading apart of the sections of the ribs to the position shown in Figs. 1 and 3.

In the modified form shown in Fig. 4 the rib is formed of main and auxiliary sections 17 and 18, respectively, and the section 18 is pivoted to the section 17, as at 19. The free end of the section 18 is provided with an opening to permit of connecting thereto the flexible bracing medium 20, the latter extending thrugh an opening 21 in the main section 17. Arranged in close proximity to the opening 21 in the main section is a shoulder 22 for limiting the movement of the auxiliary section 18 in one direction, its movement in the other direction being limited by the flexible bracing medium. The construction of the section 17 is such that the section 18 can nest therein when the umbrella is closed.

In both constructions when the umbrella is closed owing to the size of the auxiliary sections with respect to the main sections of the ribs the auxiliary sections will nest very closely within the main sections, so as not to increase the size of the latter and not to interfere in any manner with the compact folding of the umbrella.

The auxiliary sections of the ribs when the umbrella is extended or raised aflord an inner brace for the ribs, thereby preventing the umbrella from being turned inside out by sudden gusts of wind, and, as before stated, the said auxiliary sections increase the strength of the ribs and do not in any manner interfere with the compact folding of the umbrella. The auxiliary sections of the ribs are formed out of rigid material, or, in other words, of the same material as the main sections of the ribs, their contour in cross-section being different, and it is evident that owing to the fact that these auxiliary sections are formed of rigid material they will act as braces when the umbrella is raised or extended and tend materially to strengthen the main sections of the ribs.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An umbrella-rib consisting of a plurality of sections, one of said sections being recessed and adapted to have the other sec tion nest therein, said nestable section pivotally connected at one end in and slidably connected at its other end in said recessed sec tion.

2. An umbrella-rib consisting of a plural ity of sections, one of said sections being re cessed and adapted to have the other section nest therein, said nestable section pivotallyconnected at one end in and slidably connected at its other end in said recessed section, and a flexible bracing medium con nected with recessed section at a point inter mediate the points of connection between the nestable section and the recessed section.

3. An umbrella-rib consisting of a plural ity of sections, one of said sections being recessed and adapted to have the other section nest therein, said nestable section pivotally connected at one end in and slidablyconnected at its other end in said recessed section, and a flexible bracing medium connected exteriorly to said recessed section.

4. An umbrella-rib consisting of a plurality of sections, one of said sections of greater length than the other of said sections, said shorter section pivoted at one end to the other of said sections and having a hook provided at its other end, and a band surrounding said longer section and the hooked end of the shorter section for slidably connecting said hooked end to the longer section, said hooked end of said shorter section preventing the separation of the sections.

5. An umbrella-rib consisting of a plurality of sections, one of said sections of greater length than the other of said sections, said shorter section pivoted at one end to the other of said sections and having a hook provided at its other end, a band surrounding said longer section and the hooked end of the shorter section for slidably connecting said hooked end to the longer section, and a flexible bracing medium connected to said longer section at a point intermediate the points of connection between the nestable section and the recessed section.

6. An umbrella-rib consisting of a plurality of sections, one of said sections being longer than the other, said shorter section pivoted at one end to said longer section and having its other end provided with a hook and a shoulder, and a band surrounding said longer section and said shorter section between the hooked end and shoulder thereof for slidably connecting the hooked end of the shorter section to the longer section, said hooked end of said shorter section preventing the separation of the sections and adapted to permit of the bowing of the longer section.

7. An umbrella-rib consisting of a plurality of sections, one of said sections being longer than the other, said shorter section pivoted at one end to said longer section and having its other end provided with a hook and a shoulder, a band surrounding said longer section and said shorter section between the hooked end and shoulder thereof for slidably I In testimony whereof I have hereunto set connecting the hooked end of the shorter my hand in presence of two subscribing witsection to the longer section, and a flexible nesses. bracing medium connected to said longer 5 section at a, point intermediate the points of Witnesses:
